PACUSB-U2R

Overview

The PACUSB-U2R is an upstream USB port terminator manufactured by onsemi. It integrates ESD protection and EMI filtering to safeguard downstream components from electrostatic discharge events and electromagnetic interference. The device is designed for high-speed data lines, ensuring signal integrity while providing robust protection against transient voltage spikes. It operates within standard USB voltage ranges and is suitable for applications requiring reliable interface protection without complex external circuitry.

Feature Summary

• Integrated ESD protection for upstream USB ports
• Built-in EMI filtering capabilities
• Compact surface-mount package design

Applications

• Upstream USB port termination
• ESD protection for USB interfaces
• EMI suppression in USB connections

Procurement Notes

Verify the specific revision level (Rev 2 or Rev 3) against the datasheet date, as documentation indicates multiple versions from June 2010 and October 2011. Confirm package type and pinout compatibility with the target PCB layout before ordering. Ensure the component meets the required automotive or industrial qualification standards if applicable to the end application.

Selection Notes

Select this component when a dedicated upstream USB terminator with integrated ESD and EMI filtering is required. Compare pinout and electrical characteristics with similar parts like NUF2221W1T2 or PACUSBU if space or performance constraints differ. Verify that the operating temperature range and voltage ratings align with the system specifications.

Part Context

This part belongs to onsemi's portfolio of USB interface protection devices. It is functionally related to other terminators such as PACUSB-U1 and PACUSBU. These components are commonly used in consumer electronics and industrial equipment to protect USB host or device ports from damage due to static discharge and noise.

Replacement Considerations

Potential substitutes include NUF2221W1T2 and PACUSBU. Verify pin compatibility and electrical parameters before substitution. Check datasheets for differences in ESD rating, capacitance, and package dimensions to ensure mechanical and electrical fit.
